題目：功能性低甲氧基果膠/海藻酸鈉之薄膜製備技術及其特性探討
（oral-139）
With advances in science, many composite polymer materials have been developed and made for dressing to use, as polypropylene, polyethylene and polyester polymer etc., but must of composite
polymer materials belong to non-polar polymer, with disadvantages of poor absorption and non-hygroscopic, so we need to improve the surface of hydrophile or added with hydrophilic dressing in the
dressing surface, such as pectin,hydrogel etc..
隨科技的進步，人們漸漸使用各種合成高分子材料來製作敷料使 用，如聚丙烯、聚乙烯及聚酯類高分子等，但大多數合成高分子材料 為非極性的聚合物，具疏水性及吸水性差之缺點，因此需進行表面的
親水性改質或添加具親水性敷材於敷料表面，如果膠、水膠等凝膠體。
Pectin has a good hydrophile, glutinosity and stability, the use of the pectin’s hydrophile to make the dressing have good moisturizing.
果膠的優點在於有親水性、黏性及好的安定性，利用果膠之親水 性來使敷料有良好的保濕性；
Alginate has a good hydrophilicity, bio-nontoxic, biodegradable,
biocompatible.
海藻酸鈉的優點則具良好的親水性、生物無毒、生物降解、生物相 容性。
In this study, a fixed concentration of calcium chloride (0.5 wt%), the pectin (3.0 wt%) and sodium alginate (3.0 wt%) , and then soaked in calcium chloride solution (0.5 wt%) for cross-linking reaction, and change the pectin and sodium alginate in different proportion, and investigate the different proportions of swelling, moisture retention
and the effect of contact angle.
本研究是用固定濃度的氯化鈣(0.5 wt%)，將果膠(3.0 wt%)與海 藻酸鈉(3.0 wt%)複合薄膜浸泡在氯化鈣溶液中進行交連反應，並改變 不同果膠與海藻酸鈉比例，探討不同比例下對薄膜的膨潤性、保濕性 及接觸角之影響探討。
